“As an element of visual art and graphic design, line is perhaps the most fundamental. While you probably already know what a line is, graphic design will define it a little differently than the lines you studied in math class. In art, line is the path a dot takes as it moves through space and it can have any thickness as long as it is longer than it is wide. Not only can a line be a specifically drawn part of your composition, but it can even be an implied line where two areas of color or texture meet. This means that any shapes you use, even if they are not outlined, are bound by lines.”
“In addition to the types of lines, artists and graphic designers use a variety of line styles. Some lines are longer than others, some are thicker than others, while some even change direction in order to zigzag or become wavy lines with curve changes. Check out these interesting style variations.”
